Looking for a moderate to aggressive toned muffler for my 05 5.4L Triton. Have considered either magnaflow or the flowmaster super 40. I have a lariat king cab with the 5 1/2 bed if that would make a difference in tone or loudness. Any suggestions?

 

dynomax just made a nice muffler that has no drone and sounds pretty good when your on the throttle. check out the website for dynomax i think they are way under rated.
